Application filed January 2,1906. Serial No. 294,064.

To all whom it may concern:

Be it knownthat I, GEORGKIRKEGAARD, a citizen of the United States,residingv at the city of New York, in the boroughpof Brook lyn and Stateof New York, have invented certain new and useful Improvements inMachines for Capping Bottles, of which the following is a full, clear,and exact description.

My invention relates to a machine for capping bottles, and pertainsparticularly to the application of bottle-caps of the class set forth inLetters Patent No. 796,734,, comprising a cork-lined disk with dependingfingers, which are adapted to be pressed into locking engagement. withthe neck of a bottle by the circumferential movement of a cam- In thepresent application I have set forth a machine for applying caps of thisclass quickly and efficiently and in a direct and positive way.

One of the objects of the present invention machine more easy toaccomplish.

A further object of the invention is to provide a construction operatedby foot-power, which,'however, is so arranged as to secure ring inlooking the cap to the bottle.

With these and other objects in view my invention consists in theconstruction, combination, location, and arrangement of partshereinafter set forth and shown, and finally claims. In the drawings,Figure 1'.is a side elevai tion showing a complete machine embodying theprim iples of my invention; Fig. 2 is a front view of the same. Fig. 3is a section upon the line III III of Fig. 1. Fig. 4 is adetail view,partly in se( tion, of the main operating-spindle. Fig. 5 is a detailside view of l the same, taken at right angles to the. lane of i Fig. 4.Fig. 6 is a View on the line I VI of i Fig. 1 looking downward. Fig. 7is a detail view of a portion ofthc mainoperating spindie in adi'll'erent position from that of Fig. 4. 5

- Fig. 8 is a section on the line VIII 'VIII of Fig. 4. Fig. 9 is adetail sectional view on the f ,line IX IX of Fig. 4. Fig. 1 O is adetail view showing part of the mechanism of Fig. 9.

In carrying out my present. invention -1 make use of a mainoperating-spindle having a ap-applyiug head, which is positively dopressed upon a bottle, so as to engage a cap in sealing relationtherewith. In addition to I the positive means for depressing the capupon the bottle I. provide ra'ck-and-pim'on means for non-positivelyrotating the clamping-ring, so as to-lock the cap in place. Theparticular character of the non-positive connection for rotating theclamping-ring comp1; ises a volute spring in the present case which issufficiently resilient to. yield slightly in case irregularities in thebottle or in the manufacture of the cap cause an abnormal resistance.

Referringto the drawings, in which like parts are designated by the samereferencesign, 1 denotes a main frame or casing in the form of a hollowvertical standard supported from thefloor by a base portion or flanges2.

The standard is conveniently made hollow throughout the greater portionof its length, so as to contain and guide a vertically-reciprocating'rod3, to the lower end of which is attached the foot-pedal 4, pivoted at 5upon the main frame.

6 denotes a tension-spring attached to the foot-pedal 4"and serving tonormally return the same upward.,,

7 denotes the guided -toreci rocate vertically in bearings 8, projectingom the main standard 1 and having alever connection 9.with the verticalrod 3, so as to be reciprocated thereby. These details of constructionby whichithe main operating-spindle 7 is supported and moved constitutea convenient practical arrangement; but I do not desire to be limited orrestricted thereto, since any form of guiding and operating means may beused in lieu thereof.

The main operating-spindle 7 has a threaded connection 10 with the lever9, which is adjustable outward from the s indle, so as to vary the fieldof movement t ereof. The lower end of the spindle has an axially-movableindependently-revoluble core 11, nor mally spring-pressed outwardtherefrom.

The lower end of the core is axially drilled to fornr a holeor chamber11. In this chamber 1s gulded to reciprocate a plunger 12, constantlypressed outward by the spring I I a I am. operatmgspmdle 13 and carryingat its lower end a bearmgsupport 14, which is hollowed, as shown at 15,

i on its lower face, so as to receive a' bottle-cap. 7

Instead of forming the lunger 12 with straight cylindrical walls cut anannular groove or recess 16 therein, having a square upper face orshoulder 17 and a curved or beveled lower wall 18.

' 19 denote dogs having rounded ends and IIC guided to nave a slightradial movement within the core 11. These dogs bear with their innerends against the plunger 12 and contact at their otherextremities withdepending pawl-levers 20, pivoted at 21 upon the core 11. I

22 denote springs upon the core 11,which serve to normally press thepawl-levers radially outward. The lower ends of the pawl-levers areformed with offset teeth or edges 23,.the purpose of whichare to engagethe milled edges of the usual clamping-ring of a bottle-cap. In additionto the depending pawls 20 I provide de ending sprmg fingers 24, havingnotche extremities 25 and spaced annularly around the spindle, so as toreceive and hold a bottle-cap.

I provide means for rotating the core 11 independently of the mainoperating-spindle 7, and for this purpose I form a splined groove 26upon the side of the core 11, which cooperates with acorrespondingly-splined beveled gear 27, which is guided by a bracket 28from the main frame or standard 1. V

29 denotes another beveled gear meshing with the gear 27 and loosely roating on a horizontal stud or axis 30, projecting from the main frame.The stud or axis 30 is fixed with relation to the main frame and carriesloosely upon it a gear 31, meshing with a rack-section 32, ided toreciprocate vertically in themac e.

33 designates a crosshead by which the rack-section 32 is ri idlyconnected to the main operating-spindle 7. The face of the gear 31- hasalug or projection 34 thereon,

and the bevled" car 29 also has a lug or projection 35, wlaic is in thepath of and adapted to be en aged'by the lug .or projection 34.

Th bevele gear 29 has a spring connection wit its supporting-shaft 30,comprising a volute or spiral spring 36, having its ends respectivelysecured to the gear 29 and to the Stud 01' shaft 30.

, As above stated, the stud or shaft 30 is stationary, and thebevel-gear 29 is loose on the shaft and spring-pressed rotarily b itsvolutespring 36. '7 provide a stop to imit the movement of thebevel-gear under the action of its volute spring, conveniently formed bya pin 37 on the stud or shaft 30 andlocated in the path of a lug 38 onthe bevelear. In the normal relation of the parts t e bevel-gear ispressed by its volute spring intoits limiting position with the lug 38against the pin 3.7.- I

The operation is as follows: The operator bein provided .with a supplyof filled bQtt es and capsto be applied, places the bottles upon asupporting mat or pad 39 in a ial alinement with the main operating-Spin le. The operator now pushes a cap up ward between thedepending-fingers 24 until it engagesfthe bearing-support 14, whereuponthe edge of the clamping-ring will be enthe main operating-spindle is inits raised dposition, so that the core 11 is spring-presse to itsoutward limit of movement therefrom, and the plunger 12 is also sprin-pressed to its outward limlt of movement rom the core. The relation ofthe plunger and core is illustrated in Fig.7, from which it will be seenthat the dogs 19 lie inthe annular groove 16 of the plunger, so that thepawl-levers 20 are thrownradially outward, by theirs'prings 22. Theobject of this construction is to throw the pawl-levers outward, so asnot to impede 'gaged by the notches 25. During this time 4 or interferewith the insertion of the caps into the machine. The operator new placeshis foot upon the pedal 4 and depresses it, so

that the motion is communicated to the main operating-spindle. The mainoperating-spindle descends, carrying with it the core 11 and the plunger12 until the cap rests upon the bottle. The main operatingspindlecontinues to descend, however, initially compressing the sprin 13, sothat the pawl-levers 20 move inwar and en age the usual clamping-ring'of" the cap w th their toc-tned edges 23. This occurs by virtue of thecamming action of the curved or beveled wall 18 ofthe plunger 12 uponthe dogs 19. As the main operating-spindle continues to descend stillfarther the core 11 is axially pressed inward with respect theretoagainst its resilient support, so that a considerableamount of pressureis transmitted to the cap to press the latter in proper sealingrelation. upon'the bottle. In this movement the racksection 32 rotatesthe gear 31, so that the lug 34 moves in the direction of the arrow inFig. 9; but this motion is not'transmitted to the beveled gear 29, sincethere'is no connection between the two. .After a certain movement thelug 34 rotates sufficiently to cont act with the lu 35 of thegear 29,which is thereupon move by the engagement, rotating the gear 27 thesplinedcore 11 and the pawl-levers V 20., These being in engagement withthe usual milled ring of the bottle-cap, the latter Iio isturned so asto lock the cap upon the bottle. On account of the swiveled nature ofthe connection of the bearing-support 14 with the core 11 the bearin-s-upport 14 dces not partake of the motion 0 the core, but remainsimmovable upon the bottle-cap. The cap is now completely locked inprcp'er sealing relation upon the bottle,'and the bottle may be removedby releasing the pressure on the pedal 4, which permits the main operat-Now at this time the lug with the lug 34 of the bevel-gear and carried13o the spur-gear continues its movement independently of thebevel-gear. In other Words, the main operating-spindle in its upwardmovement first causes a reverse rotation of the cap-applying head, andafterward the cap-applying head moves upward with the spindle, butwithout rotation.
